The Charlotte Observer reports that Apple has filed plans to double the size of its fuel cell facility at its data center in Maiden, North Carolina to 10 megawatts.

Quote:

Fifty fuel cells adjacent to its $1 billion data center in Maiden are expected to be operating by January, Apple said in papers filed with the N.C. Utilities Commission. It will be fueled by "directed biogas" in which cleaned methane gas from a landfill is injected into a natural gas pipeline. [...]

California-based Apple says the initial 4.8-megawatt phase in Maiden began start-up and testing in October. In November it applied for an amended state permit to increase the project's size.

In North Carolina, Apple is combining its fuel cell facility with two massive solar farms to help achieve the company's goal of using 100% renewable energy at all of its data centers. At its originally planned 4.8-megwatt capacity, Apple's fuel cell facility in North Carolina was already said to be the largest in the United States not owned by a utility company.
